We recall the construction of standard families of expanded degenerations and pairs in [[1]}, Section 2.3]. They are related to the expanded degeneration family of a standard local model which is originally described in [[2]}] (see also [[1]}, Section 2.2]). Consider the standard local model
\(\underline{\pi }:\underline{U}=\mathrm {Spec}\,\frac{\mathbb {C}[x,y,t]}{(xy-t)}\rightarrow \mathbb {A}^1=\mathrm {Spec}\,\mathbb {C}[t],\)
